Local build

go >= 1.24 required

• Checkout the repo and execute go get -u in the root directory
• Run go build

Setup & run

• Run ./omnom help to list the available commands
• Execute ./omnom listen to start the web application

Configuration

Settings can be configured in config.yml config file - don't forget to restart webapp after updating.

Execute ./omnom create-config config.yml to generate a configuration file with the default configuration values.

User handling

Omnom does not store passwords. Login requires one time login token, OAuth, or a remote user header.

Login tokens can be requested via email (this requires a valid SMTP configuration in config.yml) through the web interface or can be generated from command line using the ./omnom create-token [username] login.

If you use Omnom behind a reverse proxy with authentication, you can pass the logged-in username in an HTTP header like Remote-User to automatically log in. Omnom can be configured to trust the header by setting the remote_user_header option in config.yml. Remote user header authentication can't be used with OAuth or open signups.
